Market Making With Fads, Informed, and Uninformed Traders
Mathematical Finance, EarlyView.ABSTRACT We characterize the solution to a continuous‐time optimal liquidity provision problem in a market populated by informed and uninformed traders. In our model, the asset price exhibits fads —these are short‐term deviations from the fundamental value of the asset.

Common fixed point theorems for semigroups on metric spaces
International Journal of Mathematics and Mathematical Sciences, 1999 This paper consists of two main results. The first one shows that if S is a left reversible semigroup of selfmaps on a complete metric space (M,d) such that there is a gauge function φ for which d(f(x),f(y))≤φ(δ(Of (x,y))) for f∈S and x,y in M, where δ ...

The oscillation of separately locally Lipschitz functions
Karpatsʹkì Matematičnì Publìkacìï, 2013 We prove that a function which dened on the product of two metric Baire spaces is the oscillation of some separately locally Lipschitz function if and only if it is an upper semicontinuous non-negative function which has a crosswise nowhere dense closure

Condensing Mappings and Best Proximity Point Results
Journal of Mathematics, 2021 Best proximity pair results are proved for noncyclic relatively u-continuous condensing mappings. In addition, best proximity points of upper semicontinuous mappings are obtained which are also fixed points of noncyclic relatively u-continuous condensing

Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin
Sedimentology, EarlyView.ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.

Boundaries of upper semicontinuous set valued maps [PDF]
, 2005 Let \(x_0\) be a q-point of a regular space \(X, Y\) a Hausdorff space whose relatively countably compact subsets are relatively compact and let \(F\colon X \to Y\) be an upper semicontinuous set valued map. Then the active boundary \(\operatorname{Frac}

Abstract and Applied Analysis, 2014 This paper is devoted to the various coercivity conditions in order to guarantee existence of solutions and boundedness of the solution set for the variational-hemivariational inequalities involving upper semicontinuous operators.

Identifiability of points and rigidity of hypergraphs under algebraic constraints
Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.Abstract The identifiability problem arises naturally in a number of contexts in mathematics and computer science. Specific instances include local or global rigidity of graphs and unique completability of partially‐filled tensors subject to rank conditions.

Separating sets by upper semicontinuous quasi-continuous functions [PDF]
, 2016 In this paper we characterize the pairs (A0, A1) and (A-, A+) of disjoint sets which can be separated by an upper semicontinuous quasi-continuous function.Keywords: Quasi-continuous function, upper semicontinuous function, Urysohn lemma, separating ...
